sorry for tease - the 2nd book of Braddan burials was raised on this board by myself maybe 6 months or more ago - I recall exchanges with Brian Lawson about it - though I havn't heard what has happened re FHS rewrite of their transcription.
It is not strictly true it that it was only found in the museum - when the original transcription had been done a 2nd 'copy' had been noted but not fully investigated - only the transfer of PR's to the Museum allowed further investigation when a known burial was not found and the 'copy' produced.
